An “outdoor” label is not enough. Painted walls, render, cladding and natural stone have different limits. Match the product, applicator and surface instructions before purchasing.

Product research note: Product buttons open ordinary Amazon searches, without affiliate tracking. These are categories to compare, not claims of personal testing. Check current specifications and safety instructions.
Identify what you are cleaning
Check the surface material, finish and existing damage. Ask the installer for guidance when possible. Do not assume a cleaner used on paving is suitable for render, aluminium or painted timber.
Check the product and applicator together
Verify the permitted surfaces and application method on the label. Sprayer seals, hoses and containers must be compatible with the chemical; a general garden sprayer is not automatically suitable.
- Labelled surface compatibility.
- Application, dilution and rinse instructions.
- Seal and hose chemical compatibility.
- Protection and disposal instructions.

Protect the surroundings
Plan where rinse water will go and follow label and local requirements. Keep people, pets and planting away as directed. Never mix chemicals or transfer them into food or drink containers.
Stop when the problem is not dirt
Cracking, flaking paint, persistent staining or suspected graffiti on delicate finishes may need specialist assessment. Cleaning will not fix failed coatings or water penetration.
Equipment to compare
Surface-specific exterior cleaners
Use a label explicitly compatible with the material and coating.
